Evolution depends upon genetic variations selected by natural selection each generation, so the species which reproduce the fastest generally evolve the fastest - those would be germs, viruses and other microscopic lifeforms.
Cancer cells evolve pretty fast too, unfortunately.
Luckily their adaptations are not cumulative, since they cannot reproduce outside of the patients' body and go on evolving for hundreds of years.
No, organisms die.Evolution is the change in allele frequency over time in a population of organisms.
Evolution cannot occur.
Simple statement I often use to illustrate the definition of the theory of evolution by natural selection proceeded by the definition of evolution itself. Evolution is the change in allele frequency over time in a population of organisms. Natural selection is the nonrandom survival and reproductive success of randomly varying replicating organisms.
The word evolution is a noun derived from the verb 'to evolve', which means to change over time. In science, only one type of evolution is given the title evolution in a special sense, where in a scientific context it refers solely to the changing of living organisms, the evolution of living organisms through genetic changes in populations which lead to adaptations which lead to speciation, all over long periods of time. Chemical evolution may sometimes refer to the mishmash of carbon based chains and forming aminoacids in the Precambrian seas prior to true life-formation; abiogenesis. It is not a special term of 'evolution' as that only occurs in the biological sense. It is therefore an evolution from the sense of the verb 'evolve' which merely unspecifically denotes a change.
If meiosis did not occur in sexually reproducing organisms, the chromosome number would double in each generation. Sexual reproduction results in new combinations of genetic traits.
No, organisms die.Evolution is the change in allele frequency over time in a population of organisms.
Absolutely. Evolution isn't an historical process; it is on-going as long as there is life.
Yes, cultural evolution can occur much faster than biological evolution because cultural traits can be rapidly spread and adopted among populations through communication, imitation, and technology, whereas biological evolution relies on genetic changes that accumulate over generations through the process of natural selection. This allows cultural adaptations to occur more rapidly in response to changing environments or social needs.
Evolution cannot occur.
Organisms are related to evolution through the process of natural selection. Evolution is the change in the heritable characteristics of biological populations over successive generations, which occurs as a result of natural selection acting on heritable traits. Organisms that possess advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring, leading to changes in the population over time.
One word: extinction. As long as life exists, organisms will reproduce with variation - which means per definition that evolution will occur. The only way for evolution to stop happening is for life to cease existing.
variation in the traits of organisms, heredity (the ability to pass on those traits to offspring), and differential survival and reproduction based on those traits (natural selection). These elements work together to drive the process of evolution over time.
Adaptations, such as structural changes or behavioral traits in organisms, are evidence of evolution because they reflect the process of natural selection acting on heritable variations over time. Organisms that possess advantageous adaptations are more likely to survive and reproduce, passing these traits on to their offspring, which can accumulate and lead to changes in populations or species. This gradual accumulation of adaptations is a key mechanism of evolutionary change.
there are two different rates that evolution could occur at. the first kind is gradual, which is small changes over time. the other kind is fast and it occurs when there is a big change the environment.
Common misconceptions about evolution include thinking that it is a random and purposeless process, that humans evolved from monkeys, and that evolution is always a slow process. In reality, evolution is a non-random process driven by natural selection, humans did not evolve from monkeys but share a common ancestor, and evolution can occur rapidly in response to environmental pressures.
Because it was Darwin who made it a scientifically plausible explanation, by providing a mechanism by which evolution could occur....Natural Selection.
Biological evolution is the process of changes that occur in living beings that can be passed on to their offspring. Chemical evolution is the process of changes that occur in substances. However, scientists have found that these substances have changed to form organic molecules, meaning that they have created life from nonliving substances.
